Specification of Letters Patent.

Patented Apr. 7, 1914.

T 0 all lu -J'tom it may concern.; Be it known that I, JoniafMELIsoH, a subject of the Emperorof Austria-Hungary, resid` at Benld, in the county of Macoupin and ,State of Illinois, have invented certain new and useful Improvements in Ice Crushers or Graters, of Which the following v1s a full, clear, and exact description, reference being had `to the accompanying drawlngs, forming a part hereof. 1

My invention has relation to improvements in ice Crushers or graters; and it consists in the novel details of construction `more fully set forth in the specification and pointed out in thel claim.

In the drawings, Figure l is a side elevation of the crusher, with parts broken away; and Fig. 2 is a vertical cross-section on'the line 2 2 of Fig. l.

The ,object of my invention is to construe an ice Crusher orgrater which Will find ready. service in the household, bar-rooms,

Referring to the drawings, B represents al box, receptacle or container supported at an incline on legs L, L, and provided at the rear with a hinged door D adapted to be locked by a spring latch a. No claim is made to these features per se as they are Well understood in the art. Mounted across the box at the lower or depressed end thereof in bearings 1, 1 is the shaft 2 of an open cylindrical,cutter-frame or cage, said frame comprising the terminal heads 3 composed of a. series of radiating arms, Whose outer endsare connected by longitudinal parallel bars 4, which conform to the peripheral elements of said cylinder. Disposed along the bars el ai a series of square or polygonal radially dis, osed openings o, ose of one bar being staggered with those of an adjacent bar, the said openings each receiving the square (or polygonallshank 5 of a cutter 6,

' shank 'and stem.

the shank terminating on the inside of the cylindrical frame in a screwstem 7 over which is passed a retaining` or clamping nut n .bearing against the inner face of the bar. The nuts n being on the inside of the cylinder are thus out of the Way and do not read- ;ily Work loose. As seen to best advantage in Fig. 2, the-cutter head 6 is shouldered to the outer face of the bar et, there being an offset between the shank 5 and the base of the cutter head. The cutter head or cutter proper has an inner concaved face it, tWo basal flat side faces d, an V,outer or rear flat face e and side shearing faces m, m, converging in a convex cutting edge t, the faces m, m, edge t, and face 71, tapering to a cutting tip x, the head as a Whole being disposed at an angle to the common axis of the The shaft is provided with a crank-handle C on the outside of the box, and in actual operation the shaft must be rotated in proper direction to cause the tips la: to cut into the ice as the latter gravitates -or slides toward the cutter-frame, along the inclined bottom of the box B. Immediately beneath the cutter frame is a discharge hopper II terminating in a delivery spout S for the crushed or grated ice.

The operation ofthe grater may be de-A scribed as follows: The house-wife or attendant opens the door D and introduces blocks of ice I into the box or container B and then closes the door. Thereupon rotation is imparted to the cutter-frame clockwise or in proper direction 'to cause the teeth or cutter-*heads 6 to dig into the ice as the latter4 gravitates toward the cutters along the inclined bottom of the box. The cutters grate the ice into small fragments whiclrdrop through the hopper H and discharge spout S thereof into any suitable receptacle (not shown). The cutters being readily accessible and removable, a broken cutter may be readily 'replaced by a fresh one, or a cutter may be removed and readily sharpened and quickly put back on the rotary frame. The concave face fiy is the bottom face being the face which advances toward the ice and dips toward the bottom of the receptacle, as the er approaches said bottoni. The sei7 i vters approach to Within short dist.y I e box bottom so as to better ,cut the ice and not lift 'the same'olf the bottom, the lumps of ice being thereby out or grated into small pieces il@ `desirable for various domestic and other purposes.

Features sho'Wnbut not alluded to are Well known in the art and require no detailed description in the present connection. The invention need not of course be limited in its application to the grating of ice. An inspection of Fig. l shows that the ends 'of the cutters or cutter heads, notably the faces m, m, and edges t thereof, are deflected at an angle to the radii of the cylinder along Whose periphery the cutters are disposed, the free ends of the edges being substan- 'tially tangent to the outer circles described by the cutters.

Having described my invention, What I claim is:`

An ice grater comprising a closed receptacle having a charging opening and provided with an inclined flat bottom, said bottom having a discharge opening at the de= pressed end thereof, a rotary frame mounted across the receptacle and confined therein above the depressed end of the 'inclined bottom, a series of cutters disposed on the frame and adapted to the plane of the inclined bottom 1n circular paths through the ice With the rotation of the'frame and tangenti lly to the edge of the opening over Whic the crushed ice is delivered, said cutters b ing distributed 1ongitudinally along the eriphery of the rotary frame in dist-in t rows and spaced apart, the cutters of e roW being in staggered relation with the cutters'of an `adjacent row, and dipping toward the bottom of 'the receptacle during the cutting operation.

In testimony whereof I ax my signature, 1n presence of two Witnesses.
